Super Metroid - 14% (aka. glitchless/legit low%) TAS in 0:27 by Saturn, completed in January 1, 2008, with a small improvement added during the big Metroid escape in July 2008.
This is a huge improvement to the previous 0:35 run by Terimakasih, showing a fully optimized route, alot of new and never before seen speed tricks (most noticeably the WS Lake HBJ without taking the Missile pack), and crazy boss strategies throughout the run. It beats the game with the least amount of items (if not using any major glitches such as out of room travelling and boss skips) in the fastest theoretically possible completion time of 0:27 minutes, and therefore is a must see for any Super Metroid fan.
